Abstract
The utility model relates to a slightly eccentric granulation system for plastic extrusion and thermal granulation production and aims to provide the slightly eccentric granulation system which can prolong the service life of a cutter and has the characteristics of high production efficiency, convenience in operation and simple structure. According to the technical scheme, the slightly eccentric granulation system for plastic extrusion and thermal granulation production comprises an extruder die head and a rotary cutter mechanism, wherein a plurality of circles of material discharging holes taking the axis of the extruder die head as a circle center are formed in the front surface of the extruder die head; the rotary cutter mechanism comprises a cutter rack which is positioned on a stander in a rotatable manner, a driving motor for driving the cutter rack to rotate and a plurality of blades which are arranged on the cutter rack and are matched with the material discharging holes. The slightly eccentric granulation system is characterized in that the axis of the cutter rack is parallel to that of the extruder die head, and a certain distance is reserved between the cutter rack and the extruder die head.
Description
Technical field
The utility model relates to a kind of pelletizing system, in particular for the flour milling pelletizing of plastic extruding and pelletizing process.
Background technology
Current Plastics in China is extruded the general technique that adopts concentric pelletizing of production of hot cut pellet and is produced; But the equipment of pelletizing technique and adjustment are fairly simple with one heart, but due in the process of cutting knife rotation, material with each contact of cutting knife all at identical several positions, therefore cutting knife in part quick-wearing very, pelletizing is had some setbacks, need often to change cutting knife.
Utility model content
The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, a kind of micro-eccentric pelletizing system of producing for extruding pelletizing is provided, this micro-eccentric pelletizing system can extend the cutting knife life-span, and has production efficiency feature high, easy to operate and simple in structure.
The technical solution of the utility model is:
The micro-eccentric pelletizing system of producing for plastic extrusion hot cut pellet, comprise extruder die head and rotary cutter mechanism, described extruder die head front is distributed with the discharge opening of some circles take extruder die head axle center as the center of circle, described rotary cutter mechanism comprise one be rotatably positioned knife rest in frame, for driving the drive motors of knife rest rotation and being arranged on several blades that coordinate with described discharge opening on knife rest; It is characterized in that: the axis of described knife rest is parallel with the axis of extruder die head and be the layout that keeps at a certain distance away.
Described certain distance is 5-30mm.
The beneficial effects of the utility model are: due to the axis of knife rest and the axis of extruder die head is parallel and arranged off-centre, material and contacting of cutting knife are evenly distributed on whole cutting knife, the phenomenon that the cutting knife of having avoided cutting knife concentrated wear to cause is completely scrapped too early, not only extend the service life of cutting knife, also promoted product quality.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in the figure, the micro-eccentric pelletizing system of producing for plastic extrusion hot cut pellet, comprises extruder die head 1 and rotary cutter mechanism, comprises extruder die head and rotary cutter mechanism; Described extruder die head front is distributed with the discharge opening 4 of some circles take extruder die head axle center as the center of circle; In described rotary cutter mechanism: knife rest 5 is rotatably positioned in frame (its turning cylinder 2 is positioned in frame by bearing), by the rotation of transmission system drives knife rest, (drive motors and transmission system are conventional mechanism to drive motors, therefore omit in figure), the blade 3 that several coordinate with described discharge opening is installed on knife rest; Above structure and prior art are roughly the same.
Improvements of the present utility model are: the axis of described knife rest is parallel with the axis of extruder die head and be the layout that keeps at a certain distance away; Described certain distance is determined as required, is generally 5-30mm.
Described extruder die head front (showing it is the left side of die head in figure) is distributed with the discharge opening 4 of some circles take extruder die head axle center as the center of circle, the spacing identical (size, the quantity and spacing of discharge opening are determined according to technological requirement) between the discharge opening of described adjacent turn; During work, motor drives cutting knife to rotate, and blade is cut into particle the material of extruding from die head discharge opening; Owing to being eccentric setting, contacting not of material and cutting knife can be at same position, but is evenly distributed on whole cutting knife the phenomenon that the cutting knife of having avoided cutting knife concentrated wear to cause is completely scrapped too early.
In order to guarantee the uniformity of Flow of Goods and Materials, the back side of extruder die head is also provided with corresponding shunt head 6.
In the utility model, the positive power that is adjacent to cutting knife of the size of extruder die head and die head, the rotating speed of cutting knife, determines according to technological requirement with the angle of axis etc.
Claims (2)
1. the micro-eccentric pelletizing system of producing for plastic extrusion hot cut pellet, comprise extruder die head (1) and rotary cutter mechanism, described extruder die head front is distributed with the discharge opening (4) of some circles take extruder die head axle center as the center of circle, described rotary cutter mechanism comprise one be rotatably positioned knife rest (5) in frame, for driving the drive motors of knife rest rotation and being arranged on several blades (3) that coordinate with described discharge opening on knife rest; It is characterized in that: the axis of described knife rest is parallel with the axis of extruder die head and be the layout that keeps at a certain distance away.
2. the micro-eccentric pelletizing system of producing for plastic extrusion hot cut pellet according to claim 1, is characterized in that: described certain distance is 5-30mm.
